Respiration in Succulents

Plant Venation: From Succulence to Succulents

Succulent plants dominate certain semi-arid habitats. A new study shows independent origins of 3D venation reflect hydraulic advantages for tissue succulence, and has implications for the molecular development of venation and tissue differentiation, as well as the evolution of crassulacean acid metabolism.

Salinity Tolerance of Cacti and Succulents

The salinity tolerance of golden barrel cactus (Echinocactus grusonii), ocotillo (Fouquieria splendens), saguaro cactus (Carnegiea gigantea), and Gentry’s agave (Agave parryi truncata) was tested. Plants were irrigated with a solution of EC 0.6, 5.0, 10.0, and 15.0 dS/m. Duration of treatments were 18 weeks for saguaro and 26 weeks for the other three species. In general, fresh weight, dry weig...

Cisplatin cytotoxicity is dependent on mitochondrial respiration in Saccharomyces cerevisiae

Objective(s): To understand the role of mitochondrial respiration in cisplatin sensitivity, we have employed wild-type and mitochondrial DNA depleted Rho0 yeast cells. Materials and Methods: Wild type and Rho0 yeast cultured in fermentable and non-fermentable sugar containing media, were studied for their sensitivity against cisplatin by monitoring growth curves, oxygen consumption, pH changes ...

Australia lacks stem succulents but is it depauperate in plants with crassulacean acid metabolism (CAM)?

In the flora of Australia, the driest vegetated continent, crassulacean acid metabolism (CAM), the most water-use efficient form of photosynthesis, is documented in only 0.6% of native species. Most are epiphytes and only seven terrestrial. However, much of Australia is unsurveyed, and carbon isotope signature, commonly used to assess photosynthetic pathway diversity, does not distinguish betwe...
